It is session management network element shown in Fig. 1 with session management network element below with reference to Fig. 1, policy control network element is shown in Fig. 1 Policy control network element specifically explains technical solution provided by the embodiments of the present application for PSA is Gateway Network Element shown in Fig. 1 It states.

Fig. 4 is a kind of flow chart of policy control method provided by the embodiments of the present application, and this method is for realizing in PDU meeting It is executed on multiple PSA that words include and the dosage of the first dosage monitoring example (such as business data flow grade dosage monitors example) is supervised Control.The application scenarios of this method are one PDU session of session management NE management, which may include the first PSA and second Multiple PSA such as PSA, wherein session management network element has corresponding first URR of the first monitoring key to the first PSA transmission. Under the application scenarios, step 401~step 403 as shown in Figure 4 can be executed, is held on multiple PSA of PDU session with realizing Row monitors the dosage of same business data flow grade dosage monitoring example.

Step 401: policy control network element is determined to execute on the 2nd PSA and be monitored to the dosage of the first dosage monitoring example.

Wherein, the 2nd PSA can be PSA newly-increased in PDU session.

The first dosage is monitored specifically, policy control network element can determine to execute on the 2nd PSA according to preset configuration The dosage of example monitors, which can be used for regulation and allow to access the business of the first dosage monitoring example monitoring which is A little Gateway Network Element.If policy control network element inquires preset configuration, determine that the 2nd PSA includes the gateway net in preset configuration defined In member, it is determined that execute on the 2nd PSA and monitored to the dosage of the first dosage monitoring example.Such as: if preset configuration regulation allows User accesses the business in Sohu.com on UPF2, and the business in the Sohu.com monitors what example 1 was monitored in dosage Within the scope of business, it is determined that UPF2 carries out dosage monitoring to dosage monitoring example 1.

Wherein, preset configuration can be pre-configured in policy control network element by operator, can also be by policy control net Member is obtained when executing step 401 from other network functional entities, is not limited.

It will be appreciated that determining the dosage executed on the 2nd PSA to the first dosage monitoring example in policy control network element Before monitoring, policy control network element can first know that PDU session increases the 2nd PSA newly, then, then go to judge whether on the 2nd PSA It executes and the dosage of the first dosage monitoring example is monitored.Specifically, policy control network element knows that PDU session increases the 2nd PSA packet newly Include: session management network element sends the instruction message for carrying newly-increased 2nd PSA to policy control network element, and policy control network element receives After the message, the instruction of newly-increased 2nd PSA carried according to the message determines that the PDU session increases the 2nd PSA newly.Wherein, it increases newly The instruction of 2nd PSA can serve to indicate that the 2nd PSA, can include but is not limited to the mark of the 2nd PSA, wherein the 2nd PSA's Mark may include the network function mark (Network Function Indentity, NF ID) or the 2nd PSA of the 2nd PSA Data network access mark (Data Network Access Indentity, DNAI) or the corresponding internet the 2nd PSA Protocol edition 6 prefix (Internet Protocol Version 6 Prefix, IPV6 Prefix), not limits.

Step 402: policy control network element controls information to session management network element sending strategy, and session management network element receives plan The slightly policy control information of control network element transmission.

In a kind of possible design, policy control information includes but is not limited to PCC rule, and PCC rule carries first Monitoring key, it is used to indicate the information that the corresponding strategy of PCC rule is executed on the 2nd PSA.Another is possible to set In meter, policy control information information include but is not limited to PCC rule and be used to indicate on the 2nd PSA execute PCC rule it is right The information for the strategy answered, PCC rule can carry the first monitoring key.

Wherein, it in any of the above-described possible design, is used to indicate and executes the corresponding strategy of PCC rule on the 2nd PSA Information can be the second PSA mark, the associated description of the mark of the 2nd PSA can refer to described in step 401, no longer superfluous It states.

Step 403: session management network element sends corresponding first PDR and the first monitoring of PCC rule to the 2nd PSA Corresponding 2nd URR of key.

Wherein, the first PDR may include for detecting business data flow interblock interference information；2nd URR may include using Threshold value is measured, the 2nd URR is identified by the mark of the 2nd URR.First PDR and the 2nd URR can be before step 403 by session pipe It manages network element to determine, such as: before step 403, session management network element can execute PCC rule according to being used to indicate on the 2nd PSA The then information of corresponding strategy determines and executes the corresponding strategy of PCC rule on the 2nd PSA, triggering session managed network element according to Business datum flow template in PCC rule determines the interblock interference information of the first PDR, and true for the first monitoring key Fixed 2nd URR, wherein the first PDR includes the mark of the 2nd URR, and the first PDR is associated with the 2nd URR.

Specifically, session management network element determines the interblock interference of the first PDR according to the business datum flow template in PCC rule Information may include: using PCC rule in business datum flow template in be used for business data flow detection control information as divide Group detection information addition (or matching) is into the first PDR.

Specifically, session management network element is that the first monitoring key determines that the 2nd URR can refer to: session management network element Dosage threshold value is distributed for the first monitoring key, and includes determining first in the second URR by the dosage threshold value The dosage threshold value of corresponding 2nd URR of monitoring key；Meanwhile session management network element can also be the 2nd URR distribution mark Know.Wherein, the mark of the 2nd URR can be identical with the first URR, can also be different, not limits.

In addition, in the embodiment of the present application, after session management network element determines URR for some monitoring key, Session management network element can also save the corresponding relationship of monitoring key and URR, such as: session management network element is first After monitoring key determines the 2nd URR, the corresponding relationship of the first monitoring key and the 2nd URR can be saved, So far, the relativity of session management network element saves monitoring key and URR include: the first monitoring key with Corresponding relationship between first URR, the 2nd URR.

From the foregoing, it will be observed that executing industry on the PSA that PDU session increases newly when policy control network element is determined in scheme shown in Fig. 4 Data flow level dosage of being engaged in monitors example, and other PSA that business data flow dosage monitoring example and the PDU session include are executed Dosage monitoring example it is identical when, policy control network element sends PCC rule to session management network element and is used to indicate newly-increased PSA on execute the business data flow dosage monitoring example dosage monitoring information, session management network element receive PCC rule And after being used to indicate the information for the dosage monitoring for executing business data flow dosage monitoring example on newly-increased PSA, Xiang Xin The PSA of increasing sends the corresponding URR of PDR and monitoring key, so that newly-increased PSA is according to PDR and monitoring The corresponding URR of key executes dosage monitoring, is realized with this and is executed in multiple PSA to same business data flow grade dosage monitoring example Dosage monitoring.

Specifically, session management network element is that the first monitoring key determines that the 2nd URR can in scheme shown in Fig. 4 By include in following (1)~(4) it is any it is achievable in a manner of:

(1) policy control information further includes that the first dosage threshold value of the first monitoring key and first indicate, and first Indicate that being used to indicate the first dosage threshold value is not used in the first monitoring key received before covering session management network element Dosage threshold value；Session management network element determines the dosage threshold value of the 2nd URR according to the first dosage threshold value.

Wherein, the first dosage threshold value can be according to dosage limit, the first use for the first dosage monitoring example that user contracts The dosage threshold value for the first monitoring key that the accumulative dosage and strategy control unit of amount monitoring example have issued is determining, Such as: can calculate user signing the first dosage monitoring example dosage limit and the first dosage monitoring example accumulative dosage and The difference of the dosage threshold value for the first monitoring key that strategy control unit has issued, by the difference partial threshold or Person's whole dosage threshold value is as the second dosage threshold value.

Wherein, the dosage limit of the first dosage monitoring example of user's signing, the accumulative dosage of the first dosage monitoring example May include in the signing information of user, the signing information of user can by policy control network element after PDU session establishment from UDM obtain, the signing information of user can be used for describing user for the first dosage monitoring example signing dosage limit and The accumulative dosage of first dosage monitoring example.

Specifically, session management network element determines that the dosage threshold value of the 2nd URR may include: session according to the first dosage threshold value Managed network element is using the partial amounts threshold value of the first dosage threshold value received or whole dosage threshold values as the dosage threshold of the 2nd URR Value.

For example, if the first dosage threshold value for the first monitoring key that policy control network element issues is 500M, session The dosage threshold value for the first monitoring key that the policy control network element received before managed network element issues is 200M, and meeting Words managed network element determines URR1 (200M) according to the 200M dosage threshold value of the first monitoring key, then in the implementation In, after session management network element receives the 500M dosage threshold value of the first monitoring key, 200M will not be replaced with 500M, But by the dosage threshold value (such as 300M) less than or equal to 500M as the corresponding new URR2 of the first monitoring key Dosage threshold value.

In addition, in step 402, policy control network element can also save the 2nd PSA's and the first monitoring key The corresponding relationship of first dosage threshold value, to indicate that policy control network element is to determine that executing the first dosage in the 2nd PSA monitors in fact The first dosage threshold value of the first monitoring key issued when the dosage monitoring of example.

(2) session management network element reports the accumulative dosage of the first URR to the first PSA request, and session management network element receives the The accumulative dosage of first URR of one PSA report determines available dosage threshold value according to the accumulative dosage of the first URR, and according to Available dosage threshold value determines the dosage threshold value of the 2nd URR.

Wherein, available dosage threshold value can be first that session management network element be received from tactical management network element The difference of the accumulative dosage for the first URR that the dosage threshold value and session managed network element of monitoring key receives.Optionally, First PSA reports the mark that the first URR is also carried when the accumulative dosage of the first URR, and session management network element receives on the first PSA After the accumulative dosage of first URR of report, according to the corresponding relationship of the monitoring key and URR of preservation, determine the first URR with First monitoring key is corresponding, the dosage threshold value for the first monitoring key that calculative strategy control network element issues and the The difference of the accumulative dosage of one URR, using the difference as the corresponding available dosage threshold value of the first monitoring key.

Wherein, session management network element determines that the dosage threshold value of the 2nd URR may include: session according to available dosage threshold value Managed network element is using the partial amounts threshold value of available dosage threshold value or whole dosage threshold values as the dosage threshold value of the 2nd URR.

In addition, session management network element can also update the first URR according to available dosage threshold value in this implementation, And updated first URR is handed down to the first PSA.

It should be noted that session management network element has the function of threshold value fragment, i.e. session management net in this implementation Member, which has, distributes to URR's for the partial amounts threshold value in the dosage threshold value for the monitoring key that policy control network element issues Function.

For example, if the dosage threshold value for the first monitoring key that policy control network element issues is 500M, session management The accumulative dosage that network element receives the first URR that the first PSA is reported is 200M, then available dosage threshold value is 500M-200M= 300M, session management network element can will be less than or equal to dosage threshold of the dosage threshold value (such as 200M) of 300M as the 2nd URR Value is handed down to the 2nd PSA, the dosage threshold value of the first URR is updated with 100M remaining in 300M, and updated first URR is heavy It is newly assigned to the first PSA.

(3) session management network element judges whether there is the corresponding remaining dosage threshold value of the first monitoring key；

There are remaining dosage threshold value, session management network element determines second according to remaining dosage threshold value The dosage threshold value of URR；Or in the case where no remaining dosage threshold value, session management network element is reported to the first PSA request The accumulative dosage of first URR；Session management network element receives the accumulative dosage of the first URR of the first PSA report；Session management network element According to the accumulative dosage of the first URR, available dosage threshold value is determined, and the use of the 2nd URR is determined according to available dosage threshold value Measure threshold value.

Wherein, remaining dosage threshold value can be first that session management network element be received from tactical management network element The dosage threshold value of URR is not yet assigned in the corresponding dosage threshold value of monitoring key, if session management network element will be from plan The whole dosage threshold values omited in the corresponding dosage threshold value of the first monitoring key that managed network element receives distribute to URR, Then otherwise then there is remaining dosage threshold value there is no remaining dosage threshold value.

Wherein, available dosage threshold value is repeated no more as described in mode (2).

In addition, session management network element can also update the first URR's according to available dosage threshold value in this implementation Dosage threshold value, and updated first URR is sent to the first PSA.

For example, if being handed down to the dosage threshold of the first monitoring key of session management network element before policy control network element Value is 500M, and the dosage threshold value that session management network element is handed down to the URR of the first PSA is 300M, then the first monitoring at this time The corresponding remaining dosage threshold value of key is 200M, and session management network element can all regard the dosage threshold value of 200M as the 2nd URR Dosage threshold value, can also be using a part in 200M as the dosage threshold value of the 2nd URR.If being issued before policy control network element Dosage threshold value to the first monitoring key of session management network element is 500M, and session management network element is handed down to the first PSA URR dosage threshold value be 500M, then for the first monitoring key without remaining dosage threshold value, session management network element can at this time To request the first PSA to report the accumulative dosage of the first URR, at this point, if the accumulative dosage of the first URR reported is 200M, it can Dosage threshold value is 500M-200M=300M, and session management network element can be by the dosage threshold value less than or equal to 300M (such as 200M) the dosage threshold value as the 2nd URR is handed down to the 2nd PSA, and the dosage threshold value of the first URR is updated with the 100M in 300M, And updated first URR is reassigned to the first PSA.

(4) policy control information further includes the second dosage threshold value of the first monitoring key；Session management network element root The dosage threshold value of the 2nd URR is determined according to the second dosage threshold value.

Wherein, the second dosage threshold value can be limited according to the dosage that the first dosage that can be contracted according to user monitors example The dosage threshold for the first monitoring key that volume, the accumulative dosage of the first dosage monitoring example and strategy control unit have issued Value determines；The accumulative dosage of first dosage monitoring example may include monitoring example for the first dosage in the signing information of user Accumulative dosage and the first monitoring key accumulative dosage, for example, in the signing information of dosage dosage monitor example 1 Accumulative dosage be 300M, dosage monitors the corresponding monitoring key1 of example 1, session management reported by network elements The accumulative dosage of monitoring key1 is 100M, then the accumulative dosage of the example of the first dosage monitoring at this time is 300M+100M= 400M。

Specifically, the dosage limit and the first dosage monitoring example of the first dosage monitoring example of user's signing can be calculated Accumulative dosage and the difference of the dosage threshold value of the first monitoring key that has issued of strategy control unit, will be in the difference Partial threshold or whole dosage threshold value as the second dosage threshold value.

In this approach, the accumulative dosage of the first monitoring key may include the first URR that the first PSA is reported Accumulative dosage.Such as: session management network element can receive policy control from policy control network element after determining newly-increased 2nd PSA Before information, the accumulative dosage of the first URR is reported to the first PSA request, receives the accumulative use of the first URR of the first PSA report It measures, and sends the accumulative dosage of the first monitoring key to policy control network element.Optionally, session management network element can be When sending the message for the instruction for carrying newly-increased 2nd PSA to policy control network element, first is sent to policy control network element The accumulative dosage of monitoring key, wherein the accumulative dosage of the first monitoring key can be with newly-increased 2nd PSA Instruction carry in same message, can also carry in different messages, not limit.

Specifically, session management network element determines that the dosage threshold value of the 2nd URR may include: session according to the second dosage threshold value The dosage threshold value for being less than or equal to the second dosage threshold value is determined as the dosage threshold value of the 2nd URR by managed network element.

In addition, session management network element can also update the dosage threshold of the first URR according to second threshold in this implementation Value, and updated first URR is sent to the first PSA.

Further, in scheme shown in Fig. 4, any PSA (the first PSA or the 2nd PSA) that PDU session includes is being received To PDR and URR, after carrying out dosage monitoring according to PDR and URR, which can also be to session management network element Active report URR Accumulative dosage, after the accumulative dosage that URR is received so as to session management network element, execute dosage shown in Fig. 4 a and report process；Or Person executes step 404 and step 408- step 415.As shown in fig. 4 a, which reports the process to may include:

Accumulative dosage of the PSA that step 404:PDU session includes to session management network element report URR.

Wherein, the PSA in step 404 is any PSA that PDU session includes, and can be the first PSA, or second PSA.Specifically, when the accumulative dosage for detecting business data flow with the associated PDR of URR is close or reaches the dosage threshold of URR When value, PSA can report the accumulative dosage of URR to session management network element.

Step 405: session management network element receives the accumulative dosage of the URR of PSA report, judges whether there is first The corresponding remaining dosage threshold value of monitoring key；There are the corresponding remaining dosage thresholds of the first monitoring key In the case where value, step 406- step 407 is executed；Otherwise, step 408 is executed.
